As a matter of fact, experiment has indeed observed quantum critical
behavior in the normal state above \(T_c\) . A tentative fit of the resistivity
in superconducting nickelate thin films has yielded power-law scaling with
temperature, namely \(\rho \sim T^{\alpha }\) , with \(\alpha =1.1-1.3\)  over a
wide range [1]}. Figure REF  gives an example of
the fit in Nd\(_{0.8}\) Sr\(_{0.2}\) NiO\(_{2}\)  and we obtain \(\alpha \approx 1.13\) 
from slightly above \(T_c\)  up to the room temperature. This reminds us the
strange metal above \(T_c\)  in optimal-doped cuprates and the non-Fermi liquid
in heavy fermion systems. Better numerical calculations are required in
order to establish the exact mechanism of this scaling.
